This would really awesome. I agree with Eric though: a pm system would be really useful and enhance communication. I'm keeping my fingers crossed as well! :)

Mark Twain:
"Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover."
"If you tell the truth, you don't have to remember anything."
"Never put off until tomorrow what you can do the day after tomorrow."

Will there be some kind of way to toggle a user's preferences so if they want to opt in or out of receiving the newsletter, we have that option?

Is there any chance we will ever be able to create custom distribution lists of users as well? Or, allow a comma-separated list of names to be entered into a "To:" field? (These may be more suited for the PM system than a site membership listing).

It works well except for one problem - when you focus on the title field, and then tab down to the buttons, tabbing again scrolls down to the rest of the buttons which are not meant to be visible. Perhaps you should remove the buttons you don't want to see, rather than hiding them?

May I ask - why we do not create a category-page "Mailinglist:newsgroup-a" ( or -b for different memebrlists…) with any standard text - the important is the coment-part here.-
and every member or NOT MENBER of the site can if hw/he wnats click on watch thsi page?

Than with evevry "new comment" from the admin ( or whoever has the rigts for this category) - such Mail-newsletter is send out to the watching people.
This is a typical mailin-list mainternace - if someine do not want anylonger be in the mailing-list than it is cancelled by "stiop watching this PAGE"
